The correct answer is (b) 25.
Compulsory voting is a system in which eligible voters are required by law to vote in elections. It is used in 25 countries around the world, including Australia, Belgium, and Brazil.
There are several arguments in favor of compulsory voting. One argument is that it increases voter turnout, which can lead to more representative government. Another argument is that it promotes civic engagement and a sense of duty among citizens.
However, there are also some arguments against compulsory voting. One argument is that it infringes on individual freedom. Another argument is that it can lead to voter apathy, as people may feel pressured to vote even if they are not interested in the election.
Ultimately, the decision of whether or not to adopt compulsory voting is a complex one that each country must make for itself.
